TANK-HEATER.

SPECIFICATION forming part of Letters Patent No. 596,892, dated January4, 1898. Application ned ramry 24, i897. sani No. ezines. on man.)

To @ZZ whom, it may concern:

Be it known that I, Moses TnAsDALE Lowe, a citizen of the United States,residing at Mount Horeb, in the county of Dane and State of lVisconsin,have invented a new and useful Tank-Heater, ot which the following is aspecification.

This invention relates to means for heating the water in tanks, troughs,rbc., usually provided for waterin g stock, whereby the temperature ofthe water can be modified and maintained at a certain degree in extremecold weather, so as to obviate the injurious results attendant uponstock drinking water at a low temperature approximating thefreezingpoint.

The invention consists of a heater of oblong forni to be immersed in atanker trough containing the'water to be heated and the novelcombination therewith of means for supplying air to the fire,circulating the smoke and gases, and controlling the exit thereof, allas will appear more fully in the following description and subjoinedclaims.

For a full understanding of the merits and advantages of the inventionreference is to be had to the accompanying drawings and the followingdescription.

The improvement is susceptible of various changes in theform,proportion, and the minor details of construction without departingfrom the principle or sacriticing any of the advantages thereof, and toa full disclosure of the invention an adaptation thereof is shown in theaccompanying drawings, in which- Figure lis a longitudinal section of aheater for stock-tanks, watering-troughs, dac., embodying the essentialfeatures of this invention, the dotted lines showing the covers tothefuel-pipe thrown back. Fig. 2 is a plan section thereof on the line X Xof Fig. 1.

Corresponding and like parts are referred toin the following descriptionand indicated in the several views of the drawings by the samereference-characters.

The heater is oblongin form and is designed to be placed horizontallyinthe tank, trough, or receptacle containing the water for the stock,and its body 1 may have any form in cross-section and, as shown, is ofcircular outline, with its upper portion flattened. The

body or casing 1 is closed at its ends by headsv 2, which are Iittedthereto so as to secure a water-tight joint. A pipe 3 is provided at oneend of the heater and provides a means for supplying fuel and airthereto for maintaining the ire when the heater is in opera-v tion. Apipe 4 is located contiguous to the front o r head wall of the pipe 3and forms a draft-inlet 5, and the lower portion of this pipe projectsbelow the plane of the liattened top of the body or case, so as todirect the air to the rire. A cover 6 is hinged to the pipe and closesit and the draft-inlet 5 and is provided with a damper-controlledopening 7 for admittingairtosupportcombustion. Acover A is hinged to thesame side of the pipe 3 as the cover 6 and is connected therewith bymeans of a chain or similar connection B, whereby both covers movetogether, as indicated by the dotted lines in Fig. l. This cover A actsas a deflector and prevents the smoke and gases from accumulating in theupper portion of the pipe 3 and keeps them nearer the fire, whereby agreater percentage is consumed.

A horizontal partition 8 is located in the end portion of the heater,remote from the pipe 3, and is disposed about centrally thereof, and itsouter end terminates a short distance from the rear head 2 to provide apassage C for the smoke and products of combustion when the heater is inservice, A vertical partition 9 connects the inner end of the horizontalpartition S with the bottom and sides of the heater and forms with thepartition S a smoke-chamber l0, whereby a greater extent ofradiating-surface for the heat is provided. This partition 9 isdouble-walled and curves at its top. A smoke-pipe 1l is located at ornear the middle of the heater and con1.

municates with the smoke-chamber l0 and is of a length to extend abovethe level of the water in the tank or reservoir with which the heater isto be used. An opening Dis formed in the front side of the smoke-pipeabove the partition 8 and is controlled by a damper E, so as to secure adirect draft or compel the smoke and gases to pass around the partition8 and through the smoke-chamber 10. A rod F connects the damper E with acrank portion G of a shaft H, journaled in the sides of the smoke-pipe.

The` end portion of the heater or body pro- IOO vided With the pipe 3constitutes the fuelchamber or fire-box, and the re is built therein andis supplied with fuel through the pipe 3 and with air by means of thedraftpassage 5. The smoke and products of combustion pass through thespace l2, over the horizontal partition 8, thence around said partitioninto the smoke-chamber l0, and out through the smoke-pipe l1, the heatradiated from the surface of the body warming the water in contacttherewith.

The heater is independent of the tank, trough, or other receptaclecontaining the water to be warmed and is immersed therein, suitablemeans being provided to support and secure the device in the tank at therequired elevation.

Any fuelsuch as wood, straw, bagasse, &c.-may be burned in the heaterand is admitted thereto by means of the pipe 3 upon opening the covers Gand A, as indicated by the dotted lines in Fig. l. The damper 7, inaddition to controlling the admission of air, may be utilized as a meansfor securing the cover 6 when closed. When starting the Iire or desiringto cause the same to burn more briskly, the damper E is elevated, so asto disclose the openin g D, thereby admitting of a direct draft beingsecured, and upon ciosing the openingD the smoke and gases pass aroundthe partition 8 through the smokecharnber, thence out through thesmoke-pi pe, thereby adding to the heat-radiatin g surface.

Having thus described the invention, what is claimed as new is* l. Adevice for heating water in tanks,

troughs, dro., for stock, consisting of a closed body of oblong form tobe immersed horizontally in the tank containing the water to be heatedand having a fuel-chamber at one end, a vertical pipe communicating withthe fuel-chamber and provided with a draft-inlet o1` air-passage.projecting below the inner or lower end of the said pipe, a connectedhorizontal and vertical partition at the opposite end of the body,forming a smoke-chamber, and a vertical smoke-pipe communicating withthe smoke-chambernear the said vertical partition, substantially as andfor the purpose set forth.

2. A device for heating Water in tanks, troughs, dsc., for stock,comprising a closed body subdivided by a connected horizontal andvertical partition to provide combustion and smoke chambers, asmoke-pipe extending through the combustion-chamber and communicatingwith the smoke-chamber near the vertical partition and having an openingin its side communicating directly with the combustion-chamber, and adamper for ciosing the lateral opening in the smoke-pipe, substantiallyas set forth.

3. A device for heating water in tanks, troughs, dro., for stock,comprising a closed body subdivided to provide combustion and Smokechambers, a smoke-pipe extending through the combustion-chamber andcommunicating with the smoke-chamber, and having an escape-opening inits side in direct communication with the combustion-chamber, a damperfitted to the inner end of the smoke-pipe for controlling the saidescapeopening, and means at the outer end of the smoke-pipe to admit ofthe damper being controlled from a point above the water in which theheater is immersed, substantially as de scribed.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in t-he presence of two witnesses.
